CSS (Cascading Style Sheets) is a formal language used to quickly style a web page. With it, you can style almost any HTML markup element by simply connecting the css file to the page. Using css selectors, you can select any element and set the desired parameters for displaying (color, font, size, position, etc.) There are many jokes on the Internet about working with CSS, but there is nothing complicated about it. In modern development, CSS preprocessors are used - Sass, Less, Stylus. The point in using them is better code readability and increased performance.
